I'm Ah Jun, and I share 1 Q idea every day.
The rapid development of the automotive industry has led to a surge in the number of scrap tires.
Nowadays, almost every household is equipped with a private car for the convenience of travel, which not only increases the demand for tires, but also increases the rate of their consumption, and tires need to be replaced at least once a year.
According to the statistics of the global environmental health agency, the current global stock of waste tires has reached 3 billion, and it is increasing at a rate of about 1 billion every year.
The tire recycling industry is divided into upstream and downstream, the upstream is used for raw materials, the middle end is for physical crushing and treatment, and the downstream is for the production of rubber products.
Here are a few ways to recycle scrap tires:
Tire retreading: Surface or full retreading of retreadable tires by machine to make them usable.
Cutting: Cutting waste tires by machine or by hand.
Fire repair: The machine is vulcanized at high temperature, and steel wire and rubber are added to make the tire reused.
Making tire products: machine or hand cutting and reassembling into the desired tire products.
Crushing: The machine crushes the tires into various specifications.
Cord fabric: Manually or by machine stripping the rubber on the surface of the tire and extracting the cord fabric.
Oil refining: In a closed, high-temperature environment, the rubber is converted into oil and separated from the steel wire.
Grinding: The machine grinds the tires into granules or powders, separating the steel wire and rubber in them.
Waste tire processing equipment, also known as waste tire rubber powder production line, is mainly used to grind waste tires into powder to achieve resource recycling.
Due to the large amount of waste tires, they have the potential to be recycled.
The key lies in the recovery and extraction of the basic materials, including steel wire, carbon black and oil.
The steel wire extracted from the tires can be reused in the steel mill, and the specially treated carbon black can be made into pellets for use on plastic running tracks in schools and stadiums.
The recycling price of scrap tires varies by region and time of day. For example, at the beginning of April this year, some of the J grids in the northern part of Shandong were as follows:
The recycling price of ordinary automobile tires 13-22 caliber is 0.65/kg (1300 per ton)
The recycling price of ordinary truck tires 9-12R caliber is 0.8/kg (1600 per ton)
The main recycling methods include: tyre vendors buy all kinds of waste tyres from repair shops, scrap stations and drivers, and sell them to local or overseas merchants according to their needs;
These merchants (retreaded, repaired, etc.) process the tires and then sell them to repair shops or drivers, and the processors process them further and sell the goods to more advanced merchants, who then process them for further sale.
The ways to sell waste tires include: 1 is retreaded tires, which are mainly sold to large transport fleets, especially truck fleets;
In addition, some tire stores also purchase these retreaded tires. Second, after the waste tires are crushed, they can be made into rubber blocks of various sizes, which are widely used.
It is used by a variety of manufacturing plants depending on the demand, and its main uses include the production of rubber products and sports tracks, but it can also be used to make waterproofing materials or added to asphalt to improve its stability.
In general, the waste tire processing project is indeed very good, the market is very wide and stable, many recyclers, large and small processing plants are recycling, we can go to the Internet to search and find a large number of buyers.
